SECURE MESSAGE HANDLING OF AN APPLICATION ACROSS DEPLOYMENT LOCATIONS

A method and system for secure message handling of an application across deployment locations. The application is analyzed to identify processing nodes referencing one or more data aspects having deployment constraints on locations in which aspect data in the one or more data aspects may be deployed. It is ascertained whether the one or more data aspects are accessed by an identified processing node of the application. If so, a restriction is determined for the identified processing node based on deployment constraints included in the accessed one or more data aspects and the identified processing node is deployed according to the determined restriction for the identified processing node. If not, the identified processing node or a preceding processing node is marked to indicate a required tokenization of the one or more data aspects, wherein the tokenization removes the deployment constraints for the identified processing node.
